//While I think the entertainment industry is known for it's parties and drugs//

Another generalisation from a small subset of the industry to the entire industry. Roald Dahl and J.R.R. Tolkien, for example, are not infamous for the drug-fulled orgies they didn't hold.

Although Lewis Carroll probably used laudanum (because everybody did at the time) and may well have been a paedophile.

So I guess you'll now be happy to generalise that all authors are degenerate, drug-abusing rock-spiders.
